Chapter Nine - Operation Introduction of Central Control Write
Code
The built-in central control code configured multiple projectors, It can choose the projector
control code through AIO central control software on the computer, it can also manually enter the
projector "boot", "shutdown" and "RGB INPUT1", "HDMI" control code to write into memory storage
of central control memory chip, and control the projector power on/off directly with central control
panel button.
1. Connection between the central control and the projector
1) There is an RS232 projector control line when delivery, which is used to connect the
all-in-one machine with the projector. If the serial port model of the projector is different, the adapter
shall be added;
2) The "5" pin of the central control is ground, and the "3" pin is signal output pin;
3) There are two kinds of receiving pins in serial port code of projectors of different models in various
factories, namely direct connection and crossover. However, the built-in central control has the function
of pin intelligent identification, which eliminates the need for direct connection and crossover
operation on line.
2. Software coding operation
1) After entering the computer system, open the intelligent central control management tool.
2) You can select the corresponding projector model from the existing model to see whether it is in the
list, or directly check whether the baud rate and parity check code, command code and other contents
are consistent with the control code of the projector, if consistent, you can directly select and configure
